点击提交按钮时,如何阻止被调用的onbeforeunload？
$(document).ready(function()
{
$('input:text,input:checkBox,input:radio,textarea,select').one('change',function()
{
//('BODY').attr('onbeforeunload',"return 'Leaving this page will cause any unsaved data to be lost.';");
if(
window.onbeforeunload = function() { return 'You have unsaved changes!'; }
});
});
